AMD's Radeon RX 500 series graphics card will be launching in mid-April and we know a little more about time. The latest details come from Benchlife who have shared the GPU codenames of AMD's mainstream and rebadged graphics family.
AMD Radeon RX 500 Series To Be Based on Improved 14nm LPP - Same GPU Architecture But Slightly Better Efficiency
The main difference in terms of GPU design on the Radeon RX 500 series cards would from a slightly updated 14nm LPP process node. This would deliver some efficiency gains and higher clock speeds compared to the previous variants.
14nm FinFET LPP Technology To Be Featured on Polaris 20, Polaris 21 and Polaris 12 GPUs
The GPUs utilizing the new process nodes are rebadges of the current GPU lineup. The Polaris 10 GPU will be known as Polaris 20 and Polaris 11 will be known as Polaris 21.
- 14LPP (Low Power Plus) – Enhanced version with higher performance and lower power; a full platform offering with MPW, IP enablement and wide application coverage.
The enhanced process will enable for slightly higher clock speeds at lower power consumption but we shouldn't expect the same jump as from 28nm to 14nm.
AMD Radeon RX 580 Graphics Card Specifications:
The AMD Radeon RX 580 is expected to feature a slightly higher clocked Polaris 20 XTX GPU. So this would be similar to many custom variants of the Radeon RX 480 that are currently available in the market. AMD Radeon RX 580 will feature all 2304 stream processors, 144 TMUs, 32 ROPs.
The chip itself will be clocked at 1340 MHz boost to deliver 6.17 TFLOPs of compute performance. There would be 8 GB of GDDR5 memory onboard, clocking in at 8.0 GHz along a 256-bit bus interface. The card would pump out 256 GB/s bandwidth. Expect pricing to get slightly lower than the RX 480, around $199 for the 8 GB model.
AMD Radeon RX 570 Graphics Card Specifications:
The second card to feature the Polaris 20 XL GPU would be the Radeon RX 570. This card would be similar to the RX 470, featuring a cut down Polaris core with 2048 Cores. The card would additionally feature a clock of 1244 MHz boost which given the core specs are correct, would yield compute output of 5.10 TFLOPs.
In terms of memory, we are looking at up to 8 GB of GDDR5 which will be clocked at a higher 7.0 GHz clock to deliver 224 GB/s bandwidth. Pricing wise, this card can hit around the $149 US price range.
AMD Radeon RX 560 Graphics Card Specifications:
The AMD Radeon RX 560 would be the full Polaris 11 GPU. AMD launched their RX 460 with a locked core but AIBs later launched fully unlocked variants with 1024 stream processors. The Radeon RX 560 would be similar to these with a clock speed of 1287 MHz. This will deliver a rated output of 2.63 TFLOPs along with 4 GB of GDDR5 memory along a 128-bit bus interface. Given AMD's RX 460 price to value ratio at the launch period, AMD may price this under $100 US.

AMD is expected to launch the new cards in mid of April before shipping out Radeon RX Vega series cards in late Q2 2017. The AMD Radeon RX 580 will be the fastest FinFET based card from AMD until Radeon RX Vega arrives.
